  • Start by moving all the x terms to one side of the equation and all the constant terms to the other side. To do this, subtract 5x from both sides of the equation:5x + 4 - 5x = 7x - 19 - 5xSimplifying both sides of the equation:4 = 2x - 19Next, add 19 to both sides of the equation to isolate the term with x:4 + 19 = 2x - 19 + 19Simplifying both sides of the equation:23 = 2xFinally, divide both sides of the equation by 2 to solve for x:23/2 = xSimplifying:x = 11.5Therefore, the solution to the equation 5x + 4 = 7x - 19 is x = 11.5.

  • решение:

    5x + 4 = 7x - 19 \\ 5x - 7x = - 19 - 4 \\ - 2x = - 23 \\ x = \frac{ - 23}{ - 2} \\ x = 11 \frac{1}{2} = 11.5
